2/110 Rotation of bar OA is controlled by the lead screw which imparts a horizontal velocity v to collar C and causes pin P to travel along the smooth slot. Determine the values of r and 6, where r = OP, if h = 160 mm, x = 120 mm, and v = 25 mm/s at the instant represented. %3D %3D 2/116 A helicopter starts from rest at point A and travels along the straight-line path with a constant acceleration...
Bar OA is rotating about O which causes rotation of bar CB about C. Velocity of point A is 250 (m/s) in right-hand side horizontal direction (VA = 250 i) and at this moment bar CB is horizontal and bar OA is vertical. Calculate the angular velocities of CB and AB for this instant. Also, find VB/A 100 min 50 m 250 mm
Bar OC rotates with a clockwise angular velocity Woc = 7.9 rad/s. The pin A attached to bar OC engages the straight slot of the sector. Determine the angular velocity w of the sector and the velocity Vrel of pin A relative to the sector for the instant represented. The angular velocity is positive if counterclockwise, negative if clockwise. The relative velocity is positive if to the right, negative if to the left. 340 mm O B WOC OA =...
A 10 kg bar shown is currently moving with a center of mass velocity of 1 m/s to the right. What is the angular velocity of the bar at this instant in rad/s? QUESTION 1 A 10 kg bar shown is currently moving with a center of mass velocity of 1 m/s to the right. What is the angular velocity of the bar at this instant in rad's? (gravity is acting in the vertical plane) 0.75 m V = 1...
If link AB of the four-bar linkage has a constant counterclockwise angular velocity of 50 rad/s during an interval which includes the instant represented, determine the angular acceleration of AO (positive if counterclockwise, negative if clockwise) and the acceleration of point D. 85 mm 210 mm OA 135 mm 135 mm Answers: rad/s?

please answer my questions in the picture. expecting a detailed explanation, Thankyou. why it is not vt=vocos why we dont use an at 2 In the timing mechanism shown in Figure 1, the motion of the pin A in the fixed circular slot is controlled by the guide B, which is elevated by its lead screw with a constant upward velocity t 2 ms. The radius r of the slot is 230 mm. For pin A and for the instant...
